Atlantic Treatment Plant Hydrolysis Process (THP) & Fats, Oil and Grease (FOG) Receiving Station (Construction Manager At-Risk)

Virginia Beach, VA

Crowder Construction Company was selected by the Hampton Roads Sanitation District (HRSD) as Construction Manager of the $49.3 million Atlantic Treatment Plant Thermal Hydrolysis Process (THP) and Fats, Oil and Grease (FOG) Receiving Station project. HRSD owns and operates the Atlantic Treatment Plant (ATP) located in Virginia Beach, Virginia. The ATP has a permitted design capacity of 54 MGD and is operated as a high rate activated sludge (HRAS) plant to achieve biological oxygen demand (BOD) and total suspended solids (TSS) removal. The primary objective of the project was to produce a high-quality Class A biosolids product and to provide for future increases in solids handling capability without increasing digester capacity and provide for a new FOG receiving station to feed the THP. Cambi has been selected as a sole-source supplier for the project’s THP, which makes this project the second Cambi process installation in the United States.

As the Construction Manager (CM), Crowder developed Bid Packages to obtain Process Equipment Bids, Trade Contractor Bids, and Major Contractor Bids for various portions of the Project. Each were developed in a way the Owner could make selections in its best interest and create a balance between cost and risk factors for the Project. Bids from trade and Major Contractors were evaluated with opportunities for Crowder to self-perform certain critical components of the Project for cost, schedule and other risk factors. As the CM, Crowder managed all aspects of the Construction Phase and is currently managing the Post-Construction Phase (i.e. start-up, commissioning, and process conversion, etc.) as well.
